i havent used it in a few months now. mostly cause im trying not to tip off my roommate that ive gone completely weird on him, couple more days and he'll be gone.
i did 350 hours over the course of 3 months. and its now been another 2-3 months since i stoped so i can see the regrowth. and it had some effect. theres definately less hair in the area i was messing with than when i started but. still a ton of hair. overall, it was cheap, and at the time, i had spare time. but going back, id rather have spent the time working on other things.
honestly. the 350+ hours i spent with the one-touch (on the area i was working on) was about the same ammount cleared permanantly as the first 5 hour profesional session i got done. (different area though so only a rough estimate).
if you have thousands of hours to kill, may as well try, but dont try on your face first as you dont want to ruin your facial skin. id say, if you want to invest that much time, pick up a 2nd job, and use the money from the 2nd job for profesional electrolysis. profesional will be much faster, and have a higher kill rate.
i was working on my legs when i had gotten it, and just ended up getting an epilator for my legs now.
